And those differences must be preserved—according to ethnopluralism—on the basis of an equal and shared right that all ethnicities supposedly have, that I would call 'right to exist'. This is egalitarianism, to affirm that every group have basic, natural and shared rights implies that they're all equal essentially (because rights aren't naturally given but are created out of a purpose and a motive justified by greater aims; rights are means, not foundations), and that they all have the requirements to have a place in the concert of the nations, just because they exist and present their unique features. Groups have their own way to determine their right to exist basing themselves on the goals that they have historically achieved for the survival of their people, not because they happen to hold differences with other groups. Furthermore, this would be achieved under "coexistence" and the collaboration of every ethnicity, a view that I would deem as utopian considering the nature of the national struggle of any people, which is not one of independence and autonomy only, but expansion and survival in hostile environments.
History says other thing though. I think it's a widely accepted fact that the civilizational progress of a people has as a consequence, the expansion of their culture over inferior orders (as the Jerarca said), among other things. As such, the benefits obtained by conquest are incentives for the flourishing civilization to keep growing and advancing. A prolonged status quo means death and recession.
Many of the ethnicities 'conquered' by the british weren't properly assimilated even, most of them were used just as cheap workers (read: slaves) for their industries, they were not given a place in the British culture, as it could have happened with several ethnicities under the Roman Empire. The truth is that even the differences between groups manifest in unique "styles" of conquering, and a style could leave its mark in history, or not. The Roman Empire conquered ethnicities and used them as building blocks for the progress of the Empire, and those ethnicities would stop being separate from the roman imperial consciousness
